1b all whom it may concern:

Be it known that. l, Cuantas I. LoxcnNscx-En, a .citizen of the UnitedStates, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have finven'ted certain new and useful Improvements in Gas- Engines, oi which the following is a specification.

My invention relates to speed changing mechanism "for explosive engines in whichy the mechanism for controlling the time of. ignition oi the explosive charge is .l0 vregulated by the same-means that regulates the -speed of the engine; its object being to provide a device of the above character that will be both simpleand serviceable, and one that may be readily attached to the en- -gine'. flfa'ttain these Objects by the mechanism illustrated in the accompanying drawing, in which- Figure 1 is a top plan view of my improvement and a part of the engine structure suiiicient to illustrate the 'application of my inventionthereto. Fig. 2 is a side elevation of Fig. 1; and Fig. 3 is a sectional detached 2 0 detail of a port oi lthe speed controlling mechanism.

'v Like reference numerals designate similar parts lthroughout the several views. y 1 represents the bed of he engine; 2 the cylinder secured thereto;`3 the engine shaft having one end jour- 2li naled in a bearing formed in the bed and cap 4, secured to the bed by means of bolts 5. 6 represents the liub or' the ily wheel secured to the engine shaft; 7 is a sleeve alidably mounted upon said shaft and having a peripheral channel 8 at its outer end and a conical flange 9 at $0 ita opposite end.' 9 represents lever arms pivotally lmounted upon the ily wheel, and having weighted outer ends 10, and inner arms 11 adapted to engage with the channel 8 in a manner to control the movement of the sleeve-longitudinally upon the shaft. The arms 9 may he connected by means of springs. 12 represents a hitand miss lever pivotally connected with the engine bed and having a rearwardly extending arm `13, provided with a contact roller 14 engaging with the conical tlange 9. Thel forwardly extending arm of the' lever, being broken away, is designed to contact with i "a valve operating rod in a wellknown way-to prevent admission o explosive mixture to the engine. 15 reprecents a plug secured tothecylinderand in which the sparking electrodes are mounted, and 16 represents a. '45 reciprocating igniter ro d designed to have its rear end connected to a moving part of the engine, and its forward end to make and break contact with a lever 17 y. mounted on the movable electrode, the duration of contact ofthe rod with the lever being regulated by means 50.' o! an adjustable shoe 18 mounted on the rod and adaptj ad to contact with a roller 19', upon which the rod rests,

` tha roller haii' jouraaled upon an eccentric extension 'jot'aatadlnotatablymounted nponaaedpartot engine bed in rear of the cra-nk shaft by means of a. pivot bolt 24 secured to a. bracket 25, that is preferably held in place by one of the bolts 5 that secures the cap 4 to the engine bed. One arm of the lever is provided with fork arms 26 that embrace the sleeve 7, and 27 represent rollers rotatably mounted at tlie extremities of the fork arms and contacting with the conical flange 9 of said sleeve. The other arm of the bell crank lever extends inwardly substantially parallel with the engine shaft and is provided with an opening that receives loosely the rear 4end Oia 'rod 28, that has its forward end pivot-` ally connected with a handlever 29 that is secured to the stud 21, and 30 is a common form of sector rack secured to the engine and adapt-ed tosecure the lever in adjusted position by means oi the thumb latch 31, pivi otally mounted upon the lever 29,.and adapted to engage with the toothed portion ot' the rack in the well known way. A coiled spring 32 surrounds the rear end of the rod 28 and is operative between adjusting nuts 33 on the rod and the :um of the bell crank lever in a manner to yieldingly press the rollers carried by the fork arms against the conical lla-nge on the governor sleeve.

' In operation the regular governor mechanism is regulated in the common way to allow a normal speed of the engine, and the spring. 32 is inoperative when lever 29 is held in positionl with the thumb latch engaging with the farthest notch toward th'e left-hand in the rack, and the movement of thesleeve is not influenced by lit. IE it be desired to increase the speed ofthe engine the hand lever is adjusted toward the right, compressing spring 32 and causing it to press the rollers carried by the fork arm against the flange in a manner to supplement the regular force opposing the centrifugal action of the governor mechanism, andiat the same tinie the eccentric pin carrying the roller 19 is rotated in a manner to adjust the roller to a higher plane and thus advance the time oi ignition relative to the speed of the engine.-

What I claim as my invention, and desire to secure by Letters Patent, is: A 1,. A gas engine having, in combination, speed governlngmechanlsm, lgniter mechanism, a reclprocatlng rod adapted to make and break contact with s. part of said lgnlter mechanism, means for controlling the path of movementof said rod whereby the duration of the make and break contact ls regulated, a. yielding resistance op .-andsupporting said rod, a yielding resistance opposing posing the action of said speed governingmechanism, and

IllGilDS means for regulating the force of said resistance, said being connected with said rod controlling means whereby both of said regulatng'mcans may be operated' contact-with a part of"said igniter mechanism, means for in unison.

2. A 'gas engine having, in combination, speed governing mechanism, gniter mechanism, a reciprocating rod adapted to make and break contact with a part of said igniter mechanism, means for controlling the path of movement of said rod whereby the duration of .the make and break contact is regulated, said means comprising a stud pivotally mounted in a xed part of the engine, said stud having a reduced journal portion eccentric to the axis of its pivot, a roller mounted on said journal portion the action of said speed governing mechanism, and means vfor regulating the force ofsaid resistance, said means comprising a lever secured to said stud and connected with said resistance.

3. A gas engine having, in combination, ignlter mechanism, a reciprocating rod adapted to make and break contact with a part of said igniter mechanism, means for controlling the path of movement of said rod whereby the duration of the make and break contact is regulated, a centrifugal governor adapted to control the speed of the Y engine and having a sliding sleeve forming a part thereof,

4a lever pivotally mounted upon a fixed part of the engine,

regulating means whereby' both of saidregulating means may he operated in unison.

LA gasA engine having, in combination, igniter mechanism', a reciprocatingfrod adapted to makeand' break 'controlling the path of movement of saidrrod whereby the duration o'f the make and break contact is regulated, said .means comprising a stud` piyotally mounted in a fixed part of the engine, said stud having a reduced journal portion eccentric to the axis ot lts pivot, a roller-.mounted onsaid journal portion nndsupporting said rod, an engine shaft, a fly wheel mounted thereon, a centrifugal governor adapted to control the speed of the engine and having weighted arms plvotally mounted upon said ny wheel, a sleeve slldably mounted upon said shaftl and engaging said arms, a bell crank lever '-pivotally mounted upon a-tixed part of the engine and having one arm lengaging-said sleeve in a manner to vbe moved in one direction thereby and another arm having an opening therein, an adjusting leved secured to the stud formingp'art ot the ignlter regulating means, a rod having one end pivotally 'conw Y CHARLES I: LONGEN'ECKER.
